BRUSH.

Specification of Letters Patent.

Application filed February 20, 1911.

Patented Jan. 2, 1912. Serial No. 609,602.

To all whom it may concern:

Be it known that we, ROBERT J. MONT- GOMERY and WEBsTnR H. HILL, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements Relating to Brushes, of which the following is a specification, reference bein g had to the accompanying drawings.

This invention relates to brushes and more especially to toilet brushes of the character employing a removable bristle-bearing frame whereby such frame may be readily separated from the brush-back to enable it to be more effectually cleaned than it could be if all of the parts of the brush were immovably secured together.

The object of the invention is to provide novel and effective means for detachably securing such bristle-bearing frame in place, and we accomplish this object by the means shown in the drawings and hereinafter specifically described.

That which we believe to be new will be set forth in the claims.

In the drawings :-Figure 1 is a bottom plan view of a hair-brush embodying our improvements, the bristles of the brush being broken away in several places so as to show the fixed and movable prongs or teeth that hold the bristle-bearing frame to the brush-back; Fig. 2 is a top plan view, a portion of the brush-back being broken away to show the operating devices that are located in the chamber in said back; F ig. 3 is a detail, being a vertical longitudinal section taken at line 3'3 of Fig. 2; Fig. 4 is a vertical cross-section taken at line 4:4: of Fig. 2; Fig. 5 is an enlarged detail, being a vertical cross-section taken at line 55 of Fig. 2; and Fig. 6 is an enlarged detail, being a vertical cross-section taken at line 66 of Fig. 2 and showing the engagement of the stud with the under side of the brushback whereby the operating mechanism is locked against accidental movement that might release the bristle-bearing frame.

In the several figures of the drawings in which corresponding parts are indicated by like reference characters: 10-1l indicate the brush-back, the same being formed, in the construction shown, of two thin metal plate portions spaced apart and suitably united along their edges,the numeral 10 indicating the lower plate portion and the numeral 11 the upper plate portionsaid plate portions being extended so as to form together a handle 12. In the hollow back or chamber thus formed is located the operating mechanism hereinafter described. The lower plate member 10, in the construction shown, is stamped up so as to provide a large shallow recess in which fits a bristlebearing frame of any approved construction. The bristle-bearing frame shown is of a well-known construction, made of metal and formed of a series of oval-shaped strips suitably joined together and provided on the under face with a large number of integral hollow plugs 14 in which the bristle bunches 15 are held.

At the forward end of the brush the under face of the hollow brush-back is provided with one or more fixed prongs or teeth 16-two being shown in the drawings, see Fig. 1,which project inward slightly over the recess in which rests the bristle-bearing frame and which serve to retain the bristlebearing frame in place at that end of the brush. Turning now to the means employed for further securing such bristlebearing frame to the brush-back-17 and 19 indicate respectively two arms arranged transversely of the brush and located in the chamber of the hollow back, each of said arms, in the construction shown, resting upon the face of the lower member or plate 10 of said hollow back and bent, as shown, to conform substantially to the stamped shape of such plate member. The outer end portion of each arm is turned to adapt it to project through a suitable small opening cut in the said plate member 10such projecting ends forming small prongs-indicated respectively by 18 and 20that are adapted to be moved under the edge of the bristlebearing frame 13 (see Figs. 1 and 1) and thereby, in connection with the prongs or teeth 16, hold said frame securely in place. To insure the arms 17 and 19 being always capable of being moved back and forth in a straight line and thereby be better adapted to engage the bristle-bearing frame and be disengaged from it, the inner ends of the arms are made to interlock or fit one within the other. This is accomplished by cutting a large straight-sided notch 21 in one arm, the inner end of the other arm being made so as to fit snugly therein. The arms 17 and ,this pivot 27 and at short distances therefrom the lever is connected by pin-and-slot connections 29 and 30 to the arms 17 and 19 respectively. It will be evident that by reason of the construction and arrangement of parts described the arms 17 and 19 will be projected or drawn in simultaneously and uniformly upon the lever 28 being moved, and that accordingly as they are moved in or out the prongs on their ends will engage and hold the bristle-bearing frame or be disengaged therefrom. WVhen the prongs are disengaged from said frame the frame can easily be removed from the brush-back as the forward prongs 16 are not sufficient to hold said frame 13 without the cooperation of the movable prongs 18 and 20. To

. insert the frame 13 in place all that is neces sary to do is to have the lever so positioned as to hold the arms moved outward, slip the forward end of the bristle-bearing frame beneath the stationary prongs 16, press the bristle-bearing frame down into its recess in the face of the brush-back, and then by a movement of the lever draw the arms 17 and 19 inward, which will cause their respective prongs 18 and 20 to engage under the said frame 13.

As shown the lever 28 is bentsee Fig. 2so that its free end may project through a suitable opening in the edge of the brushback, either in the handle portion 12 or adj acent thereto. Such projecting end is best provided with a slight lip or flange that can be engaged by the users finger nail to draw the lever out enough to enable it to be grasped. It is advisable that means for locking the lever against accidental move ment be provided and to that end we provide on the under face of the lever a stud, as 31, which at its lower end is adapted to project into a small opening 32 cut in the plate member 10. The lever 28, as is best shown in Fig. 3, is bent downward at its outer portion and is to be made of a material having springiness enough to cause the stud to be forced down at all times, and hence when the stud is moved over said opening 32 it will dro therein and the lever will thereby be sufliciently locked to insure its remaining unmoved unless by design of the user. As shown in Fig. 6 we reduce the portion of the stud that enters the opening 32 and also round that portion, the rounding being done to enable it to be moved more readily out of the opening, as will be readily understood.

What we claim as our invention, and desire to secure by Letters Patent, is

1. In a brush, the combination with a chambered back and a bristle-holding frame, of movable clamping means located in said back above said frame and adapted to engage said frame.

2.
